JUSTIFICATION OF THE CHOICE OF A METHOD OF RECEIVING PREPARATION OF A DETAIL "CASE" Vereshchagina A. S., Ph.D. (Engineering), e-mail: osa321@gmail.ru Ivanova M.V., Ph.D. student, Assistant e-mail: ivanova777888@yandex.ru Kharitonov A.A., Graduate students, e-mail: andrey.hharitonov@yandex.ru Novosibirsk State Technical University, 20 Prospekt K. Marksa, Novosibirsk, 630073, Russian Federation Abstract In this work the topical issues of mechanical engineering devoted to the choice of a method of receiving preparation at manufacture of body details are considered. Article contains detailed information on a detail "Case": weight, imposed performance specification, deviations, roughness, material, geometrical parameters and also for the existing technological process and preparation a material capacity factor, time for processing of this product. The main methods of receiving preparations extended today are considered. Their merits and demerits, in relation to the chosen detail option " Case " are specified. The analysis on the basis of which the alternate method of receiving preparation for manufacture of the product " Case " was chosen as the most rational and economically justified, in comparison with other methods of receiving preparation is carried out. Keywords Mechanical engineering, workpiece, material utilization factor, labor input, detail, technological process.
